Abstract
(EN)
In one example, a system comprises a central unit and a radiating point located remotely from the central unit and communicatively coupled to the central unit. The radiating point is configured to provide radio frequency signals to a coverage zone via one or more antennas. The system further comprises a radar sensor communicatively coupled to the radiating point and configured to capture image data in the coverage zone of the radiating point, wherein the radar sensor includes a plurality of transmitters and receivers coupled to an antenna array. One or more components of the system are configured to determine user detection data for users in the coverage zone based on the image data captured by the radar sensor and adjust the power consumption of the radiating point based on the user detection data.

Dans un exemple, un système comprend une unité centrale et un point rayonnant situé à distance de l'unité centrale et couplé en communication à l'unité centrale. Le point rayonnant est configuré pour fournir des signaux de radiofréquence à une zone de couverture par l'intermédiaire d'une ou de plusieurs antennes. Le système comprend en outre un capteur radar couplé en communication au point rayonnant et configuré pour capturer des données d'image dans la zone de couverture du point rayonnant, le capteur radar comprenant une pluralité d'émetteurs et de récepteurs couplés à un réseau d'antennes. Un ou plusieurs composants du système sont configurés pour déterminer des données de détection d'utilisateur pour des utilisateurs dans la zone de couverture sur la base des données d'image capturées par le capteur radar et ajuster la consommation d'énergie du point rayonnant sur la base des données de détection d'utilisateur.
